BENJAMIN L. WOOD, OF TAUNTON, MASSACHUSETTS.

IMPROVEMENT IN CARRIAGE-THILLS.

Specification forming part of Letters Patent No. 57,809, dated September4, 1866.

To all whom it may concern:

Be it known that I, BENJAMIN L. WOOD, of

, Taunton, in the county of Bristol and State resented in theaccompanying drawings, of

which- Figure l is a top view, Fig. 2 a side elevation, and Fig. 3 alongitudinal section, of it as applied to a carriage thill or shaft andfront axle.

The purpose of my invention is to enable a shaft or pole to be readilyapplied to or detached from an axle, as circumstances may require.

In the drawings, A denotes the axle, or a part thereof, and B the shaft.0 U are the starts, and D the safety-strap eye-piece, usually applied toan axle, they being held in place by a yoke, E, and two nuts, F F,screwed thereon, the whole being as shown in the drawings.

The bolt a, which extends from one start to the other, and underordinary circumstances is a screw-bolt provided with a nut, I fastenfirmly in the starts in any proper manner, as it is to be immovable withreference to them.

In carrying out my invention, instead of forming the rear part of theshaft, or the iron bar or plate 1) thereof, with an eye to go betweenthe starts toreceive the bolt thereof, I construct it with a hook, c, tohook upon and project below the bolt, and I make such hook with anaperture, (2, going through it where it extends below the bolt to. Thisaperture is to receive the safety-strap G, usually affixed to the shaftand axle, such strap being carried through the aperture and applied tothe shaft and axle in manner as represented in the drawings.

Within the hook, and so as to lap around the bolt a and be fastened tothe shaft by a clamp, H, I usually apply a strap of leather or othersuitable substance, I, it being to preward connected or buckledtogether; or, in

the place of such, a tongue or strip of leather or other suitableflexible material, fastened to the shaft, may berun through the apertureof the hook.

I prefer, however, to use the safety-strap in the manner specified, asby so doing I make it answer two purposes, and save the necessity of anauxiliary strap or its equivalent.

It will be readily observed that with my improvement or invention, asapplied to an axle and its shafts or pole, the attachment of such shaftsor pole to or their disconnection from the axle will be a very easy andquick operation.

I claim as my invention 1. The improved shaft or pole-connection, asmade with a hook, c, and an aperture, 01, therein, arranged with thestart-bolt a, and to receive a strap or its equivalent, as specified.

2. The arrangement of the safety-strap G to pass through the aperture ofthe hook, as described.

3. The combination of a strap or its equivalent, to go through the eyeof the hook, with such hook and the shaft or its equivalent.

4. The arrangement and application of the anti-friction strap I with theshaft or its equivalent and the hook 0, provided with an aperture, (I,as and for the purpose described.-

BENJAMIN L. WVOOD.
